Using Postman to Launch an EC2 Instance via API Calls

As I mentioned in this post on region and endpoint match in AWS API requests, exploring the AWS APIs is something I’ve been doing off and on for several months. There’s a couple reasons for this; I’ll go into those in a bit more detail shortly. In any case, I’ve been exploring the APIs using Postman (when on Linux) and Paw (when on macOS), and in this post I’ll share how to use Postman to launch an EC2 instance via API calls.

Before I get into the technical details, let me lay out a couple reasons for spending some time on this. I’m pretty familiar with tools like Terraform and Pulumi (my current favorite), and I’m reasonably familiar with AWS CLI itself. In looking at working directly with the APIs, I see this as adding a new perspective on how these other tools work. (I’ve found, in fact, that exploring the APIs has improved my usage of the AWS CLI.) Finally, as I try to deepen my knowledge of programming languages, I wanted to have a reasonable knowledge of the APIs before trying to program around the APIs (hopefully this will make the learning curve a bit less Continue reading

Deploy Stateful Docker Containers with Amazon ECS and Amazon EFS

At Docker, we are always looking for ways to make developers’ lives easier either directly or by working with our partners. Improving developer productivity is a core benefit of using Docker products and recently one of our partners made an announcement that makes developing cloud-native apps easier.

AWS announced that its customers can now configure their Amazon Elastic Container Service (ECS) applications deployed in Amazon Elastic Compute Cloud (EC2) mode to access Amazon Elastic File Storage (EFS) file systems. This is good news for Docker developers who use Amazon ECS. It means that Amazon ECS now natively integrates with Amazon EFS to automatically mount shared file systems into Docker containers. This allows you to deploy workloads that require access to shared storage such as machine learning workloads, containerizing legacy apps, or internal DevOps workloads such as GitLab, Jenkins, or Elasticsearch. 

The beauty of containerizing your applications is to provide a better way to create, package, and deploy software across different computing environments in a predictable and easy-to-manage way. Containers were originally designed to be stateless and ephemeral (temporary). A stateless application is one that neither reads nor stores information about its state from one time that it is run Continue reading

Scientists Create a Long-Distance Cryogenic Microwave Quantum Network

There’s been quite a bit of fanfare around quantum computing during the last few years, with experts predicting that quantum computers will help fuel the growing computational demands of artificial intelligence, as well as forming the backbone of an unhackable internet. But beyond the hype is the reality that quantum computers are still some ways from being commercially viable, as researchers continue to resolve issues like accuracy, size and how to build a superconducting electrical oscillators that are used in some quantum chips need to be cooled down to near-absolute zero temperatures, otherwise the problem of Quantum Device Lab at study co-author quantum entanglement, two particles become linked in a way so that whatever happens to one particle, it also immediately occurs to the other, no matter the distance. Having proven that a cryogenically based, long-distance quantum network is indeed possible, the team is now working to construct a 30-meter (98.4-foot) quantum link. See more over at ETH Zurich’s

BGP Hell Is Other People

If you configure a newsreader to alert you every time someone hijacks a BGP autonomous system (AS), it will probably go off at least once a week. The most recent one was on the first of April courtesy of Rostelecom. But they’re not the only one. They’re just the latest. The incidences of people redirecting BGP, either by accident or be design, are becoming more and more frequent. And as we rely more and more on things like cloud computing and online applications to do our daily work and live our lives, the impact of these hijacks is becoming more and more critical.

Professional-Grade Protocol

BGP isn’t the oldest thing on the Internet. RFC 1105 is the initial draft of Border Gateway Protocol. The version that we use today, BGP4, is documented in RFC 4271. It’s a protocol that has enjoyed a long history of revisions and a reviled history of making networking engineers’ lives difficult. But why is that? How can a routing protocol be so critical and yet obtuse?

My friend Marko Milivojevic famously stated in his CCIE training career that, “BGP isn’t a routing protocol. It’s a policy engine.” When you look at the decisions of Continue reading

How to Find a Networking Assistant

The networking assistant role is a major and important one in every business and organization. They are responsible for building, designing, implementing, and maintaining complex systems that keep employers in an organization productive. They work on computer networks that are the most critical part of every organization. They install, support, and maintain computer systems, including Intranet, Extranet, LAN (Local Area Networks), WAN (Wide Area Networks), phone system, network segments, and all other data communication systems.

Where to Find a Networking Assistant

When looking to hire a networking assistant for your business or organization, you need to spend time on some credible sites. Hiring a networking assistant shouldn’t stress you out, you only need to look in the right places to find the best for your business.

Remote User Access in the Era of COVID-19

The worldwide lockdown due to COVID-19 has given me an opportunity to reflect on many aspects of life and work.

Rolling With The Punches: Shifting Attack Tactics & Dropping Packets Faster & Cheaper At The Edge

On Cloudflare’s 8th birthday in 2017, we announced free unmetered DDoS Protection as part of all of our plans, regardless if you’re an independent blogger using WordPress on Cloudflare's Free plan or part of a large enterprise operating global network infrastructures. Our DDoS protection covers attack vectors on Layers 3-7; whether highly distributed and volumetric (rate-intensive) or small and sneaky. We protect over 26 million Internet properties, and at this scale, identifying small and sneaky DDoS attacks can be challenging, especially at L7. In this post, we discuss this challenge along with trends that we’ve seen, interesting DDoS attacks, and how we’ve responded to them so that you don’t have to worry.

When analyzing attacks on the Cloudflare network, we’ve seen a steady decline in the proportion of L3/L4 DDoS attacks that exceed a rate of 30 Gbps in recent months. From September 2019 to March 2020, attacks peaking over 30 Gbps decreased by 82%, and in March 2020, more than 95% of all network-layer DDoS attacks peaked below 30 Gbps. Over the same time period, the average size of a DDoS attack has also steadily decreased by 53%, to just 11.88 Gbps. Yet, very large Continue reading

Video: Networks Are (Not) Secure

It’s amazing how many people still believe in Security Fairy (the mythical entity that makes your application magically secure), fueling the whole industry of security researchers who happily create excruciatingly detailed talks of how you can use whatever security oversight to wreak havoc (even when the limitations of a technology are clearly spelled out in an RFC).

In the Networks Are Not Secure (part of How Networks Really Work webinar) I described why we should never rely on network infrastructure to provide security, but have to implement it higher up in the application stack.
